-;; These convert sequences such as `mov #k,r0; add r15,r0; mov.l @r0,rn'
-;; to `mov #k,r0; mov.l @(r0,r15),rn'.  These sequences are generated by
-;; reload when the constant is too large for a reg+offset address.
-
-;; ??? We would get much better code if this was done in reload.  This would
-;; require modifying find_reloads_address to recognize that if the constant
-;; is out-of-range for an immediate add, then we get better code by reloading
-;; the constant into a register than by reloading the sum into a register,
-;; since the former is one instruction shorter if the address does not need
-;; to be offsettable.  Unfortunately this does not work, because there is
-;; only one register, r0, that can be used as an index register.  This register
-;; is also the function return value register.  So, if we try to force reload
-;; to use double-reg addresses, then we end up with some instructions that
-;; need to use r0 twice.  The only way to fix this is to change the calling
-;; convention so that r0 is not used to return values.
